In the [MiMC_hash.sol line 27](https://github.com/HarryR/ethsnarks/blob/master/contracts/MiMC_hash.sol#L27), is doing `r = ( r + in_x[i] ) + hash(in_x[i], r) mod q`.
Looking to the MiMC paper https:/…

We are currently using `keccak256` as hash function to calculate sparse merkle tree leafs.
We could use a more friendly zk-snark hash such as `MiMc` or `Poseidon` just in case we add zero-knowledge…

Currently we use MiMC/e7r91 for our merkle trees. MiMC/e7r46, which is less secure but could be 'acceptable', reduces this by about 50%.
This would reduce the number of constraints in our circuits …

Hey Harry,
Interesting work you've got going here!
I was looking at using your Solidity implementation of MiMC together with circomlib's javascript implementation, but it doesn't seem to give the…

Hi Harry,
In [this post](https://ethresear.ch/t/cheap-hash-functions-for-zksnark-merkle-tree-proofs-which-can-be-calculated-on-chain/3176/10) you say that it may be acceptable to reduce the number …
